Another pharaoh who belongs to this group is Tutkheperre Shoshenq. His period of rule within this dynasty is currently uncertain, although he is now thought to have governed Egypt early in the 9th century BC for a short time between Osorkon I and Takelot I. The next ruler at Tanis after Shoshenq V was Osorkon IV. This pharaoh is sometimes not believed to be a member of the 22nd Dynasty since he only controlled a small portion of Lower Egypt together with Tefnakhte of Sais—whose authority was recognised at Memphis—and Iuput II of Leontopolis.
